This Newbury Bluetooth Speaker by Back Bay Audio uses two 45mm precision audio drivers to fill an entire room with music and a dual-passive-radiator design to create an enhanced bass response. With its IPX4 rating, this speaker is splashproof so you can enjoy your favorite music during after-work showers, beach parties, or pool-side lounging. This Bluetooth speaker can also connect with another speaker for an immersive stereo experience, one speaker as the right channel and the other as the left channel, playing music in-sync from your device. Blast music all day long and never worry about recharging with its 24-hour battery life.
